我需要帮助。 如何基于FLIGHTYPE A = Arrival和D = Departure配对成一行？

Answer 1

再次内部加入同一个表。在下面的示例中，f1将包含到达和f2离开。

select f1.*, f2.*  -- replace with the list of columns you need
from flights f1
inner join flighs f2 
    on f1.FLIGHTNO = f2.FLIGHTNO
    and f1.FPL_ID <> f2.FPL_ID
    and f1.FLIGHTYPE = 'A' and f2.FLIGHTYPE = 'D'
